Service Mode:

This mode allows more detailed operation tests and trou-bleshooting, to enter press Signal & Extra Rinsesimultaneously with the power on.

While in Service Mode the following tests can be per-formed:

Quick Spin Test = Delay Start & Extra Rinse: This accel-erates the drum motor from 0 to maximum RPM over afew minutes. Note: Stay with the washer during this test,out of balance detection is bypassed and the door may

not lock. Press the Start/Pause button during the test to holdits spinning speed for 10 minutes before going back to QuickSpin Test Mode.

Cycle Count = Press the Signal button to see how manytimes the unit was used.

Soft Ware # = Press the Soil button to see the software ver-sion information.

Fast Time Down = Start cycle then enter service mode.Press the Temp button to advance to the next cycle.

Fault Code Test = Press the Spin button to view the storedfault codes – then turn Jog Dial to view error codes (PushStart/Pause while the code is displayed to view the cycle num-ber when the error occurred).Peripheral (Main PCB) input Tests; Select Extra Rinse (display shows ln).1. Water Temperature; Turn the Jog-Dial so that the HeavyDuty LED is turned on. The Water Temperature will be dis-played in Fahrenheit.2. Door status; Turn the Jog-Dial so that the PermanentPress LED is turned on. The door status will be displayed(OP if open, CL if closed).3. Door lock; Turn the Jog-Dial so that the Sanitize LED isturned on. The door lock Switch status will be displayed (UL ifunlocked, Lo if locked). 4. Water Frequency; Turn the Jog-Dial so that the BeddingLED is turned on. The Water Frequency will be displayed.

Quick Test ModeNote: This test erases all faults and memory:

To enter press Soil, Signal, & Power simultaneouslywith the power off.1. All LED’s light up and the washer beeps as it en-ters the Quick Test Mode. 2. The unit displays the software version for asecond then clears the EEprom. If EEEE is dis-played the PCB ass’y is defective. 3. When the version is displayed, turn the Jog-DialCCW so that the version disappears. Each step ofthe Jog-Dial displays the following; cycle count, wa-ter level frequency, water temperature, EP condition,test, spin, version.Press the following keys to test the various compo-nents.Water valves: (lock the door first) Press Temp Key tocycle in this order: Pre-Wash, Cold, Bleach, Cold &Bleach, Hot & then off.Door Lock/Unlock: Press Spin Key.

Circulation/Drain Pump: Press Signal Key. Water heater: Press Soil Level Key.Motor test: When either Test or Spin is displayed onthe LCD, press Start/Pause key.

Test mode: You can test the clockwise and counter-clockwise movement of the motor. However, the waterlevel must satisfy the heater water level (24300) to enterTest mode. Spin mode: You can test the motor at a high rpm.

Heater Error Hr36

(Heater

Relay)

This can be a short or a wire disconnected to the heater circuit. Thiscan also be problem with the tub contacting the heater or if the wa-ter in the tub is frozen or there is no water. The error is triggered bytemperatures above 145C. If the heater has no error, this occursbecause of a PBA relay malfunction. Check the wiring harness tothe heater.

An Hr error occurs if the steam heater, is faulty, replace it.

9E1 EMC Filter issue or a noise spike from an external device

Overflow error OE1E

Water is supplied continually because the water level detectiondoes not work. - Verify the drain is working properly, the water leveldetection does not work and water is supplied continually. Verify thewater valves shut off fully. Finally check the water level sensor.

TemperatureSensor Error

29 The washing heater temperature sensor in the tub has an error.Check the connections for the washing heater temperature sensorconnector.

Unbalance

Error

dC10

Check the type of laundry. Check whether it may cause an unbal-anced situation.- Educate the consumer in this case, to presspause, reposition the load or remove a few items. Press start tocontinue and complete the wash cycle.

Mems or Har-ness Failure

8E Check MEMS PCB ,Main PCB & Wire-harness

FoamingDetected SUdS

Sd

This occurs when too much foaming is detected. It is also displayedwhile foaming is removed. When the removal is finished, the normalcycle proceeds. (This is one of the normal operations. It is an errorfor preventing non-sensing faults.)

8E1 Front MEMS Sensor problem: Restart the cycle

If the error continues,

Replace Mems sensor

8E2 Rear MEMS Sensor problem: Restart the cycle

If the error continues,

Replace Mems sensor

Check whether the washing machine is level to the floor with respect to the original position of the washing machine prior

to service Doing this now will reduce the need for a redo call and customer dissatisfaction

Vibrations can shorten the lifetime of the product

Water valve connections for the Detergent Drawer

When installing a washer and dryer onthe first, or second floor, do not exceedthis leg adjustment height for stability.

Samsung washers and dryers can be stacked to maximize usable space. An optional stacking kit is available for purchase from your Samsung retailer

CAP-FIXER DC67-00307A

HOSE-HANGER DC62-10278A

When using non-HEdetergents, or usingtoo much detergentfor the water hard-ness and soil level ofthe clothing, oversudsing will occur.When this happens

there will be leaks outof the detergentdrawer and door.Please advise con-sumer of proper de-tergent usage.

It is normal for a small amount of waterremaining in Detergent Drawer after itcompletes washing. Bleach is usuallyflushed out into the tub at the beginningof the washing. Also, its compartment iswashed again during the following rinsecycle, removing any remnants.

Location considerations

Do not install your washerin areas where watermay freeze, since your

washer will always main-tain some water in its wa-ter valve, pump, and hoseareas. This can causedamage the belts, thepump, hoses and othercomponents. Operatingtemperature should be

above 60°F/16°C.
